Andrew Murray

Vice President and General Manager Mobile Analytics, SAP

Andrew brings an extensive background in sailing and a passion for all things nautical. He enjoys sharing his enthusiasm for boating with youth and helping out in the boat shop in his free time. He lives in Albany with his family.

Amber Rich

Waterside Workshops Executive Director

Our executive director believes that the only way to lead is from the ground-level. Born and raised in rural North Carolina by traditional artisans, she spent her young life getting her hands dirty working in a blacksmith’s shop and on the family farm. Upon going to college, she chose to study architecture, because it seemed to fuse her passion for preserving the environment, and inspiration as an artist, but quickly found it required too much time quietly working in an office. At Waterside, she oversees fundraising, budgeting projects, organizing staff and interns, and ensures the activities of the organization serve the community to the fullest extent possible. She is committed to going the extra mile for young people in need, even if that means walking most of the way.

Helder Parreira

Berkeley Boathouse Program Director

Board Secretary

Born and raised in the Azores Islands, Helder developed a love of traditional boats as a very young child. Helder is a UC Berkeley alumni holding a degree in Archeology. His academic studies took him around the world studying ancient cultures and often studying their watercraft. Tiring of academic pursuits, and craving working with his hands, Helder moved back to California to study traditional wooden boat building, but continued his connection with is homeland. Helder has worked in the Azores not only as an underwater archaeologist, but has also apprenticed with one of the last master Azorean whaleboat builders. His passion “for all things maritime Portuguese” has also taken him to mainland Portugal where he has worked with traditional bateira builders of the Aveiro region of northern Portugal. He hopes to educate people young and old, as well as further his own knowledge of the time-honored craft, and to establish a community of people who are passionate about wooden boats.
